what is the equation of the line in standard form through each point? (3,1) & perpendicular to -4c + y - 1= 0
Which table corresponds to the equation? Y = 4x + 1?
Answer:
3rd one down
Step-by-step explanation:
(1,5), (2,9), (3,13), (4,17)
The table C is Solution for the Equation.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
given:
Equation: y= 4x+ 1
When x= 1
y = 5
and, x= 2
y= 8 + 1= 9
and, x= 3
y= 12 + 1= 13
and, x=4
y = 16 + 1 = 17
Thus, the solution for the Equation is (1, 5), (2, 9), (3, 13) and (4, 17).
Hence, the table C is Solution for the Equation.

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 5 grams were from whole grains. Did Osvoldo meet his goal? Why?..
Answer:
Answer: Osvoldo did not meet his goal.
Step-by-step explanation:
Total carbohydrate ate by Osvoldo = 220 g
carbohydrate from grains = 55 g
Percentage of carbohydrate of grain is
\begin{gathered}=\dfrac{\text { carbohydrate taken from grains}}{\text {Total carbohydrate}} \times 100\\\\= \dfrac{55}{220} \times 100= 25 \%\end{gathered}
=
Total carbohydrate
carbohydrate taken from grains
×100
=
220
55
×100=25%
Goal of getting carbohydrate from grains = at least 30%
but he ate only 25% of carbohydrate
Hence, Osvoldo did not meet his goal as he ate less carbohydrate than his goal.
If the Weight of Candy Is proportional to the price and 12 ounces of candy is $3.00,dollars how much is 20 ounces of candy?
Answer:
$5.00
Step-by-step explanation:
if you divide $3.00 by 12 you get $0.25 which is what your paying per ounce so all you would have to do once you get how much your paying per ounce is multiply your per ounce number ($0.25) by your total amount of ounces (20) and you then get your answer $5.00. Hope this makes sense!

) What is the distance between this pair of points?
(-5, 2) and (-5, 6)
Answer:
[tex]d=4[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d=\sqrt{(-5-(-5))^2+(6-2)^2}[/tex]
[tex]d=\sqrt{(-5+5)^2+(4)^2}[/tex]
[tex]d=\sqrt{(0)^2+16}[/tex]

-Combine like terms:
[tex]-6 < 3x - 4x[/tex]
[tex]-6 < -x[/tex]
-Switch sides:

Find the mode and the mean of the following set showing number of hours of operating life 25 flashlight batteries:20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Answer:
mode: 22
mean: 21
Step-by-step explanation:
For mode, look for the number that occurs the most (22). I remember this because MODE kinda sounds like MOST. Remember that the mean is just another word for average. I remember this because I think its MEAN that they'd make another word for average, although the term average is way easier to remember. So, add all numbers (525) and divide them by 25.
525 divided by 25= 21
(it might be safe to double check my work)
The mean of the set showing number of hours of operating life 25 flashlight batteries is, 21.8
The mode of the set showing number of hours of operating life 25 flashlight batteries is, 22
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The set showing number of hours of operating life 25 flashlight batteries is,
⇒ 20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Now, We can arrange the numbers in ascending order as;
⇒ 18, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 22, 22, 22, 22, 22, 22, 23, 23, 23, 23, 24, 24, 25, 26
Thus, The mean of the set is,
⇒ Mean = 18 + 19 + 19 + 20 + 20 + 20 + 21 + 21 + 21 + 21 + 22 + 22 + 22 + 22 + 22 + 22 + 22 + 23 + 23 + 23 + 23 + 24 + 24 + 25 + 26 / 25
⇒ Mean = 545 / 25
⇒ Mean = 21.8
And, The mode of the data set is the most often number in data set.
Hence, The mode of the set = 22

Opoint T

Answer:
B-
point s
Step-by-step explanation:
I just did the quiz, this is the correct answer
Point S is the endpoint of the rays.
Option B is the correct answer.
What is a ray?In geometry, a ray is a straight line that starts from a specific point (called the endpoint) and extends infinitely in one direction.
A ray can be thought of as a part of a line that has one endpoint and continues indefinitely in one direction.
We have,
A ray is a line that starts from a specific point and extends infinitely in one direction.
The starting point of the ray is called the endpoint, and the other end of the ray extends indefinitely.
Therefore, a ray does not have an endpoint in the direction it extends, but only at its starting point.
From the figure,
The ray SR, SU, and ST have one common starting point.
i.e Point S.
Thus,
Point S is the endpoint of the rays.
